Installation Instructions for OpenCart 2.x
OpenCart 2.x introduces the Extension Installer feature, which we will use:
Unzip the downloaded ZIP file into a new folder
Login to your OpenCart admin panel and go to Extensions > Extension Installer. Upload the file nitropack.ocmod.zip, which is in the folder you created in Step 1.
NoteIf you receive an error, this most probably means that your OpenCart FTP settings are not properly configured, or FTP is not enabled on your server. To resolve this, follow these steps:
STEP A: Go to System > Settings > Edit > FTP and update your FTP settings. After you are done, try uploading NitroPack again. If it does not work and you receive an error, follow step B.
STEP B: Go to this link: http://www.opencart.com/index.php?route=extension/extension/info&extension_id=18892 and download and install the Quickfix for the OpenCart Extension installer. Before installing, make sure that the Quickfix extension is compatible with the version of your OpenCart. After you are done, try uploading NitroPack again. If this does not help, follow step C.
STEP C: Unzip the contents of nitropack.ocmod.zip in a new folder. Copy all files from the upload/ folder over your current OpenCart installation preserving the directory structure. No original files will be overwritten. Go to Extensions > Extension Installer and upload each file from the folder _ocmod/.
Login to your OpenCart admin panel and go to System > Users > User Groups, click Edit of your admin user group (i.e. Top Administrator) Enable Access and Modify permissions for tool/nitro. Click the Save button.
Go to Extensions > Modifications and click the Refresh button on the top right
- Go to Tools > NitroPack. Review the settings and click Save Changes.
Congratulations! You have successfully installed NitroPack!
